BALL-BEARING FOR VERTICAL SHAFTS.

Specification of Letters Patent.

Patented Oct. 5,] 909.

Application filed December 6, 1907. Serial No. 405,366. 1

'a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Ball-Bearin s for Vertical Shafts, of which the following is a specification.

The principal object of the present invention is to provide a compact, reliable and comparatively inexpensive bearing suitable for use in connection with among other things vertical rotary converters and motors and in which the ball bearings which carry end and side thrusts shall be fully lubricated.

In the drawings, Figure 1, is a View, principally in central section, illustrating theupper bearing or part of the bearing, and F 1g. 2, is a similar view. illustrating the lower hearing or part of the hearing.

In the drawings 1, is a housing having cylindrical internal walls and also having a tubular neck 2, extending upward and inward from an opening in its base. Externall the neck and the adjacent portion of the ase of the housing constitute a seat for the hard washer 3. The internal cylindrical wall of the housing is raised and constitutes a seat for the outer ring 4, of the annular bearing. Through the neck 2, extends the shaft 5. 4

6, is a nut or cap rigidly connected to the shaft, as shown,'by means of a slot andkey. 7. Externally the cap is outwardly and downwardly flanged at its base so as to-provide a depending portion .which encircles the upper end of'the neck. On top of the ange 1s a seat for the inner ring 8, of the annular bearing and beneath the flange is a seat for the hard washer 9, of the thrust bearinglO.

11, is a ring attached to the ca 6, as by a screw-thread and serving to ho d to place the inner ring 8, of the annular bearing.

' 12, is a cover for the housing or casing 1,

7 which is properly fixed and supported.

. 13, is an opening by means of which the oil which fills the bottom part of the housin 1, included betweenits cylindrical wall an V the wall of the neck, is introduced to-a height sufiicient for lubricating both the thrust and the annular bearing. The top of the neck is sufficiently high to maintain the proper level of oil for accomplishing this purpose.

The construction and arrangement of the part of the bearing shown inFig. 2, is substantially the same as is shown in Fig. 1, ex- 'cept that the cover 12, and the cap or nut 6, are provided with openings through which the shaft 5, extends. Furthermore the thrust bearing is omitted as are also the seats shown in Fig. 1, for its reception. The nut 6, is

1 provided as in Fig. 1, wiiih a seat for the an nular bearing 14, and it is also provided with a seatl5, which may be used for a second annular hearing which it is not necessary to show and which is not infrequently omitted in practice.

What I claim as new and desire to secure by Letters Patent is:

1. A hearing for vertical shafts comprising, an annular ball bearing, a housing inserving to secure said inner ring in place upon its seat, substantially as described.

, 2. A bearin for vertical shafts compris ing, a housing aving a tubular necl extending upward and inward through its base and constituting in conjunction with the housin floor a" seat for one member of-a thrust caring and also in conjunction with the walls of the housing an oil well space, a nut or cap having a depending flange constituting a seat for the inner ring of an annular ball bearing and a seat for the other member of a thrust bearing, a thrust bearing arranged in the oil well space, and an annular bearing interposedbetween the housing and nut and arranged in the oil well space, substantially as described.

3. A bearing for vertical shafts comprising, a housing having a tubular neck extending upward and inward through its base and constituting inconjunction with the'wall of the housing an oil well space, a nut arranged in the housing, an annu ar ball bearing arranged in the oil weli spa e and In testimony whereof I have hereunto illilterposed betwefen-thi:1 -rim of thg nut and signed my name. t e inner Wall 0 the ousing, an a thrust L bearing encirclingthe neck and interposed SAMUEL EVELAND' 5 between the under side of the nut and.- the \Vit-nesses:
